Silent Mode

Build output verbosity in Packem is driven by a debug/verbose toggle rather than a "silent" switch. The only verbosity-related control that exists in the config is debug.

debug

The debug option enables verbose logging. It is part of BuildOptions:

import { defineConfig } from '@visulima/packem/config'

export default defineConfig({
  debug: true,
})

When enabled, Packem emits additional logger.debug(...) output (for example, where the config file was found) and passes debug through to jiti, which loads your config and entry files.

Environment flags

The --production and --development CLI flags (mutually exclusive) set the build environment, which in turn affects defaults such as minification. They do not silence logging, but they are the primary way to switch a build's mode from the command line:

packem build --production
packem build --development

What does not exist

For accuracy, note the following are not available:

• No silent: true config key.
• No --silent or --quiet CLI flag.
• No logLevel / verbosity config option.

If you need quieter output, the practical lever is to leave debug off (its default), which suppresses the verbose debug stream.
